2 Sheets-Sheot 2 Filed March 1926 ill) is an inverted conicel recess 6 'treni out of the bottom ol? which opens the discharge outlet for the molten metal. As best shown in lFigs. 2, 3 and s the discharge outlet is in the 'form of a cylindrical passage 7 ot considerable diameter, forned in a hollow walled casting 8. The lirehrick 9 of which 'the bottom wall of the auxiliary chamher is formal, p'e'l'erably coves the top ot the cast ing so as to protect it Inore or 'from the action of the molten glas& The casting is kept cool by means of water fiowing into the seine through a pine 10, and out agan through a pipe ll These pipes may both he connected to the lower end of the casting, the Water being conpelled to flow to the top hy means of partitions 12 rising upwerdly from the bottom of the charnher within the hollow Wells to a. point near the 'top of the chamher; the disposition ot' the pipes 10 and 11 being such that the water must rise to the top ot the casting on one side ot the partitions, hezt'ore it can reach the outlet pipe 'on the othersidc. r

Below the auxiliary chai'nhcr are parallel beans 14 and 15, Conveniently structural 'll heams. Secured to these heans are members 16 having horizontal channel, shaped tracks 17 lying ou the inncr sides ot the heams. Rolling along these tracl s Wheels 18 that support a horizontal novahle valve 19 that has a flat upper surface in contact With u fiat hotton 'face of the outlet casting'. The 'valvc is made holloW and it is cooled by Water fiowiug into the same through a pipe 20 and out through a discharge pipe 21. Une end ot the val /e has a ehisel edge 22 which, as the Valve is .moved from its open position, as shown in Fig. 3, to the closed position shown in Fig. 2, cuts through the column ot noltcn glass leaving' the discharge outlct. The Valve is provided with an openin; 253 exicnding Verticaliy through the same and having a diameter equal to that oi' the discharge 'passage 7. M ovable Vertical y in this opening is a hollow plunger 24-. ln the :u''angeont shown, the plungcr is pivol'aily connected at its lower end, as indicated at 25, to one arm ot a hell cranl; !ever 28 that is pivotcd at its olhow, as ai'. 27, holwccn depending cars 28 integral with the valvc. Normally when the valve is closed, ur metal hein; withdrawn froni the furnacc, the plunger extends upthrough the dis;- chart'c passage 7 and projects a short distan e into the conical ri-ccss 6 as shown in Fie When the outlet paseage is to he opened` the plungor is li'st drawr down until its 'top is liush With the top of the vlve as shown in Fig. 3, and then 'the valve is novwl laterzlly alone' its iracks until it i I^il-ill` ol' the lower end ol' the outlet pas- :mwa

When the valve is; open. as shown in Fig.

:L th mohon glass iows down in :L solid column through the discharge passage until the valve is again closed. To close the Valve it is n'oved toward the right in Fig. 3, first severing the column of noltcn glass and stoppug the llow. The plunger is then moved up, forcin the Inolten material. in 'the outlet passage ahead of it into the hot mass constituting the supply of niolten glass in the auxiliary chainhcr. Since the plunger accurately tits the outlet passage, the hounding walls of the latter will he scraped clean as the plunger, rises. 'l`heretore, since the more or ,less chilled glass thet is pushed up out ot' the outlet passage becomes cffcctiveiy re-heated when it entere the large body ot nolten glass, the 'flow of glass Will he free and unobstructed when the 'valve is opened, and there will he no ehilled residue that will. he deposiied ou the casting table.

The plunger is coolcd iu any desired Way, conveniently hy introducing into the interor thereot' cooling Water through a pipc or conduit 30, and allowing the water to discharge through a pipe or conduit 31. In order to insu'e that the cool water Will always reach the top ot' the plunger, the inlet pipe 30 is connected to a stand pipo 32 that extends upwardly in the plunger and has its open end terninating a short distance helow the top of the plunger. The cooling water theretore enters the plunger at the top.

'the Valve and the plunger may he operated in any suitable Way.. ln the arrangeinent shown, the bcams 14: and 1.5 andthe tracks 17 are extended outwardly beyond the end ot the auxiliery turnace ehamher. Mounted On the extended portions of the tracks is a Wl'eeled truck 35 connected to the Velve by a rod 36 so that the truck and the Value move in unison With each other. Depcnding 'from the truck is an air cylinder 37 having a pisten rod 38 between which and the hell. crank level' 26 is urranged a connccting rod 39. When air is turned into the air cylinder to inove the pisten red in one direction, the hell crank lever is swung so as to i'aise the plunger. When air is ad- Ini'tted to the cylinder to move the pisten rod *in the opposite direction, the plunger is retracted. The Vulve may he operatedhy a second air cyliuder 40 n'iounted above the outer ends ot the tracks and having e pisten rod 41 connected to the Valve.

The auxiliary turnace chanber is located ai a considerahle distance ahove the floor on which the casting table rests, so that the (able, indicated at 50, may he moved underneath the outlet 'froni the auxiliary ehamber along tracks or rails 51, or otherwise, to peruit the rnolten glass to he deposited di rectly on the tahle from the 'urnace When the vulve is opened.

While l have illustratcd and described with particularity onl a single preterred toi-ni ol' my invention, l do not desire to be lili) V the gloss fcmnining omooi limited to *the omct structuml lctoila ths illustra'tecl and described; hot iiloml to co'vcr all forms and rr'ohgements which come within the dcihitions of my iivenlio consttuting the appcnclcd claim&

I claim:
